What did Jean Baptiste van Helmont discover?

Jan Baptista van Helmont (1580-1644) partially discovered the process of photosynthesis. He grew a willow tree in a weighed amount of soil. After five years, he discovered that the willow tree weighed about 74 kg more than it did at the start.

How did Jan van Helmont discover photosynthesis?

Jan Van Helmont wanted to prove plants use materials from the soil to perform photosynthesis. So he performed an experiment where he took a pot of soil and a willow seedling and weighed the pot of soil and the willow tree separately. Then he planted the willow tree by sunlight and watered it every day.

How did van Helmont determine that plants do not obtain their food from the soil?

In this experiment, he carefully weighed a young willow shoot, and then planted it in a large container whose soil he had also carefully dried and weighed. In this way, van Helmont demonstrated that plants do not simply take up soil as they grow, and concluded that water was the sole source of this increased weight.

Who named CO2?

Joseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s. At room temperatures (20-25 oC), carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable.

Which plant did Ingenhousz use?

Priestley then placed a sprig of mint plant in the container and discovered that after several days the mint had produced some substance (later recognized as oxygen) that enabled the confined air to again support combustion.

What happened to the light energy after it reached the willow plant?

What happened to the light energy after it reached the willow plant? Write down the specific equation for photosynthesis and relate the equation to this question. The light energy transforms Walter m carbon dioxide into carbohydrates a nutients the plant needs, in releases oxygen.
